產品檢測裝置、產品檢測系統及應用於其上的產品檢測方法 Product testing device, product testing system and product testing method applied thereon

本發明是有關於一種產品檢測裝置、產品檢測系統及應用於其上的產品檢測方法，尤其是有關於一種具有多個傳輸埠而能同時對多個待測產品進行自動檢測的產品檢測裝置、產品檢測系統及其產品檢測方法。 The present invention relates to a product testing device, a product testing system and a product testing method applied thereon, in particular to a product testing device that has multiple transmission ports and can automatically detect multiple products to be tested at the same time, Product inspection system and product inspection method thereof.

通用序列匯流排(USB)是一種連接於電腦裝置與外接裝置之間的規格或標準，也是一種電源或信號輸入/輸出介面的技術規範。以硬體外型來說，目前通用序列匯流排(USB)的連接頭或傳輸介面可分成Type-A、Type-B和Type-C(又稱為USB-C)三種類型。其中Type-C有別於Type-A和Type-B的最大特點在於其連接頭的上下層相同，也就是沒有正反面的區別。 Universal Serial Bus (USB) is a specification or standard for connecting between computer devices and external devices, as well as a technical specification for power or signal input/output interfaces. In terms of hardware appearance, the current universal serial bus (USB) connector or transmission interface can be divided into three types: Type-A, Type-B and Type-C (also known as USB-C). The biggest difference between Type-C and Type-A and Type-B is that the upper and lower layers of the connector are the same, that is, there is no difference between the front and back.

此外，USB電力傳輸(USB Power Delivery，簡稱USB PD)是一種由USB開發者論壇所發布的關於USB的充電協議或標準，也是一種可進行快速充電的技術。目前USB-C PD所制訂的最新版本為3.0，且是針對Type-C類型的傳輸介面。 In addition, USB Power Delivery (USB PD for short) is a USB charging protocol or standard published by the USB Developer Forum, and is also a fast charging technology. At present, the latest version of USB-C PD is 3.0, and it is a transmission interface of Type-C type.

相較於以往標準之USB 2.0最大供電功率的2.5瓦特(W)、USB 3.0最大供電功率的4.5瓦特(W)、USB電池用途充電(Battery Charging，簡稱BC)最大供電功率的7.5瓦特(W)，目前USB-C PD的供電功率範圍可達到15至100瓦特(W)。因此，高功耗用電的電子裝置例如筆記型電腦、平面電視等，也可以使用Type-C類型的電源線進行供電。 Compared with the previous standard USB 2.0 maximum power supply of 2.5 watts (W), USB 3.0 maximum power supply power of 4.5 watts (W), USB battery charging (Battery Charging, referred to as BC) maximum power supply power of 7.5 watts (W) , the current power supply range of USB-C PD can reach 15 to 100 watts (W). Therefore, electronic devices with high power consumption, such as notebook computers, flat-screen TVs, etc., can also use Type-C power cords for power supply.

正因為可支援USB-C PD的相關周邊電子產品可在相對高電壓或大電流的條件下進行運作，使得這些產品可能會面臨許多包括電源充電、相容性、安全性或保護機制設計等技術問題。因此，相關產品在出廠前的產線測試就相當重要。目前針對USB-C PD產品的產線測試可包括有例如過電流保護(OCP)、過電壓保護(OVP)、低電壓保護(UVP)等電壓或電流項目的檢測。 Because related peripheral electronic products that can support USB-C PD can operate under relatively high voltage or high current conditions, these products may face many technologies including power charging, compatibility, security or protection mechanism design. question. Therefore, the production line test of related products before leaving the factory is very important. Current production line testing for USB-C PD products may include testing of voltage or current items such as overcurrent protection (OCP), overvoltage protection (OVP), and undervoltage protection (UVP).

然而，目前技術針對USB-C PD檢測所設計的設備只能一次對一台待測件(Device Under Test，簡稱DUT)進行測試，且是由檢測人員以手動方式進行電壓/電流的切換或調控，並以目測方式觀察其過程與結果。這樣的方式不但工時長而造成檢測人員的負擔，更容易產生誤判等問題。是以，如何開發出一個能夠同時應付產線上多個被測件之檢測的檢測系統，已成為開發者或業界所不可忽視的重要議題。 However, the current technology designed for USB-C PD testing can only test one device under test (DUT) at a time, and the testing personnel manually switch or control the voltage/current. , and visually observe its process and results. This method not only causes long working hours and burdens the inspection personnel, but also is more prone to misjudgment and other problems. Therefore, how to develop a testing system that can handle the testing of multiple DUTs on the production line at the same time has become an important issue that cannot be ignored by developers or the industry.

以下係提出實施例進行詳細說明，實施例僅用以作為範例說明，並不會限縮本發明欲保護之範圍。此外，實施例中之圖式係省略不必要或以通常技術即可完成之元件，以清楚顯示本發明之技術特點。 The following examples are provided for detailed description, and the examples are only used as examples to illustrate, and do not limit the scope of protection of the present invention. In addition, the drawings in the embodiments omit unnecessary elements or elements that can be completed with ordinary techniques, so as to clearly show the technical characteristics of the present invention.

現以一第一實施例進行本發明所提出之產品檢測裝置、產品檢測系統及應用於其上的產品檢測方法的實施說明。請同時參見第1A圖和第1B圖，其中第1A圖為本發明的一產品檢測裝置100的平面示意圖；第1B圖為本發明的一產品檢測系統1進行USB-C檢測應用的示意圖。如第1A圖和第1B圖所示，該產品檢測系統1主要包含有一電腦裝置50、一電源檢測儀器60與該產品檢測裝置100。而該產品檢測裝置100主要包含有一電路板10、一處理單元11、多個USB-C傳輸埠21~26和多個檢測連接埠31a~38b，其中該處理單元11、該些USB-C傳輸埠21~26與該些檢測連接埠31a~38b設置於該電路板10上。 A first embodiment is now used to describe the implementation of the product detection device, the product detection system and the product detection method applied to the present invention. Please refer to FIG. 1A and FIG. 1B at the same time, wherein FIG. 1A is a schematic plan view of a product detection device 100 of the present invention; FIG. 1B is a schematic diagram of a USB-C detection application of a product detection system 1 of the present invention. As shown in FIG. 1A and FIG. 1B , the product testing system 1 mainly includes a computer device 50 , a power testing instrument 60 and the product testing device 100 . The product detection device 100 mainly includes a circuit board 10, a processing unit 11, a plurality of USB-C transmission ports 21-26 and a plurality of detection connection ports 31a-38b, wherein the processing unit 11, the USB-C transmission ports The ports 21 - 26 and the detection connection ports 31 a - 38 b are disposed on the circuit board 10 .

本發明的該產品檢測裝置100與該產品檢測系統1是提供給產線進行多個被測件(DUT)或待測產品之檢測，特別是 針對USB-C(或稱Type-C)類型的電子產品。如第1A圖和第1B圖所示，所設置的該些USB-C傳輸埠21~26是以六個作示意，而該產品檢測系統1是以對兩個USB-C待測產品41、42進行檢測應用作示意，即該些USB-C傳輸埠21、22可提供該些USB-C待測產品41、42形成連接。可以理解的是，若所檢測的USB-C待測產品的輸出/輸入埠只有一個時，則該產品檢測裝置100最多可以檢測六個此類的USB-C待測產品，或者視需求也可僅檢測一個此類的USB-C待測產品。 The product inspection device 100 and the product inspection system 1 of the present invention are provided for the production line to inspect a plurality of DUTs or products to be inspected, especially For USB-C (or Type-C) type electronic products. As shown in FIG. 1A and FIG. 1B , the USB-C transmission ports 21 to 26 are shown as six, and the product testing system 1 is for two USB-C products to be tested 41 , 26 42 is used for testing as an illustration, that is, the USB-C transmission ports 21 and 22 can provide the USB-C products under test 41 and 42 to form a connection. It can be understood that, if there is only one output/input port of the detected USB-C product to be tested, the product detection device 100 can detect at most six such USB-C products to be tested, or it can also be used as required. Only one such USB-C DUT is detected.

其次，該些檢測連接埠31a~38b是提供給該電源檢測儀器60進行連接，且其中的檢測連接埠31a~36b的設置是相應於該些USB-C傳輸埠21~26。詳細來說，每一個USB-C傳輸埠會相應一組數目為兩個的檢測連接埠(即V+端與GND端)，例如USB-C傳輸埠21對應的是兩檢測連接埠31a、31b，USB-C傳輸埠22對應的是兩檢測連接埠32a、32b，而該電源檢測儀器60可使用四條傳輸線分別進行連接。於此實施例中，傳輸線的一端可分別對所要檢測的USB-C待測產品41、42所連接的USB-C傳輸埠21、22所相應的檢測連接埠31a、31b、32a、32b加以連接，而其另一端則連接至該電源檢測儀器60。 Secondly, the detection connection ports 31a-38b are provided for the power detection instrument 60 to be connected, and the configuration of the detection connection ports 31a-36b corresponds to the USB-C transmission ports 21-26. Specifically, each USB-C port corresponds to a set of two detection ports (ie, the V+ terminal and the GND terminal). For example, the USB-C port 21 corresponds to two detection ports 31a and 31b. The USB-C transmission port 22 corresponds to the two detection connection ports 32a and 32b, and the power detection instrument 60 can be connected with four transmission lines respectively. In this embodiment, one end of the transmission line can be respectively connected to the detection port 31a, 31b, 32a, 32b corresponding to the USB-C transmission ports 21, 22 connected to the USB-C DUT 41, 42 to be detected , and its other end is connected to the power detection instrument 60 .

該電源檢測儀器60可為習知技術的檢測裝置，主要是用來對被測件(DUT)的輸出/輸入功率(W)的表現進行檢測。視設計的不同，該電源檢測儀器60可設計具有多個檢測頻道(CH)，例如六個，故以第1B圖的配置來說，可以僅連接一台電源檢測儀器60就可同時檢測六個USB-C待測產品。當然，其他實施例所使用的電源檢測儀器也可能僅具有一個檢測頻道而已，針對此種狀況，該產品檢測裝置100就必須連接多台此類的電源檢測儀器以進行檢測應用。 The power testing instrument 60 can be a testing device of the prior art, and is mainly used to test the performance of the output/input power (W) of the device under test (DUT). Depending on the design, the power detection instrument 60 can be designed to have multiple detection channels (CH), such as six, so for the configuration shown in FIG. 1B, only one power detection instrument 60 can be connected to simultaneously detect six channels. USB-C product under test. Of course, the power testing instruments used in other embodiments may only have one testing channel. In this case, the product testing apparatus 100 must be connected to a plurality of such power testing instruments for testing applications.

須注意的是，在第1A圖和第1B圖是以十六個(即八組)的數目設置該些檢測連接埠31a~38b，這是因為本發明的該產品檢測裝置100還可具有設置於該電路板10上的多個Type-A 傳輸埠27、28，在此是以兩個作示意，而該些Type-A傳輸埠27、28分別對應一組檢測連接埠37a、37b和38a、38b。是以，第1A圖和第1B圖中的該些Type-A傳輸埠27、28可提供給一至兩個Type-A待測產品形成連接。換句話說，該些檢測連接埠31a~38b的設置數目是相應於該些USB-C傳輸埠21~26與該些Type-A傳輸埠27、28這兩種類型。本發明關於對Type-A待測產品的檢測應用將於後續進行說明。 It should be noted that in FIG. 1A and FIG. 1B, the detection ports 31a-38b are provided in a number of sixteen (ie, eight groups), because the product detection device 100 of the present invention may also have settings. Multiple Type-A on the circuit board 10 The transmission ports 27 and 28 are shown as two here, and the Type-A transmission ports 27 and 28 correspond to a set of detection ports 37 a and 37 b and 38 a and 38 b respectively. Therefore, the Type-A transmission ports 27 and 28 in FIG. 1A and FIG. 1B can be provided for one or two Type-A products under test to form a connection. In other words, the number of the detection connection ports 31 a ˜ 38 b is corresponding to the two types of the USB-C transmission ports 21 ˜ 26 and the Type-A transmission ports 27 , 28 . The application of the present invention to the detection of the Type-A product to be tested will be described later.

另一方面，該產品檢測裝置100還具有設置於該電路板10上的一後端連接介面12。於此實施例中，該後端連接介面12採用USB型式的設計，用以提供該電腦裝置50使用相應的傳輸線形成連接。類似地，該電腦裝置50可為習知技術的裝置，也就是可為筆記型電腦或桌上型電腦，主要在於本發明的該電腦裝置50載有一檢測程式，用以提供使用者或檢測員進行檢測的控制和觀看檢測結果。該檢測程式可呈現為一種視窗介面，且可以指示該產品檢測裝置100來運作本發明的產品檢測方法。 On the other hand, the product detection device 100 further has a rear connection interface 12 disposed on the circuit board 10 . In this embodiment, the rear connection interface 12 adopts a USB type design to provide the computer device 50 with a corresponding transmission line to form a connection. Similarly, the computer device 50 can be a device of the prior art, that is, a notebook computer or a desktop computer, mainly in that the computer device 50 of the present invention carries a detection program for providing users or inspectors with Take control of inspections and view inspection results. The inspection program can be presented as a window interface, and can instruct the product inspection apparatus 100 to operate the product inspection method of the present invention.

承上所述，本發明所提出的該產品檢測方法為將該處理單元11設置成一韌體以提供執行，或是於該處理單元11所電連接的一快閃記憶體(未顯示於圖式)中儲存成一運作程式碼以提供該處理單元11直接執行。詳細來說，在該電路板10上還可設置對應各USB-C傳輸埠21~26並支援USB-C PD通訊協定的硬體單元，例如Type-C埠控制器(Type-C Port Controller，簡稱TCPC)來分別控制USB-C傳輸埠21~26。 Based on the above, the product detection method proposed by the present invention is to set the processing unit 11 as a firmware to provide execution, or a flash memory (not shown in the drawings) electrically connected to the processing unit 11 ) is stored as an operation code to provide the processing unit 11 for direct execution. Specifically, the circuit board 10 can also be provided with hardware units corresponding to the USB-C transmission ports 21 to 26 and supporting the USB-C PD communication protocol, such as a Type-C Port Controller (Type-C Port Controller, TCPC for short) to control USB-C ports 21~26 respectively.

另一方面，可使用例如Type-C埠管理(Type-C Port Manager，簡稱TCPM)的軟體技術來設計以微控制器(MCU)作設置的該處理單元11，特別是以可支援對多個USB-C待測產品進行檢測或是以能管理USB-C PD通訊協定的多埠為目的來進行程式設計與編碼。雖然在第1A圖和第1B圖中未示出，但可以理解的是所述的各Type-C埠控制器是分別電連接於該些USB-C傳輸埠21~26與該處理單元11之間。 On the other hand, software technology such as Type-C Port Manager (TCPM) can be used to design the processing unit 11 configured with a microcontroller (MCU), especially to support multiple The USB-C DUT is tested or programmed and coded for the purpose of managing multiple ports of the USB-C PD protocol. Although not shown in FIG. 1A and FIG. 1B, it can be understood that each of the Type-C port controllers is electrically connected between the USB-C transmission ports 21 to 26 and the processing unit 11 respectively. between.

本發明的特徵除在於設計多個USB-C傳輸埠以同時對多個USB-C待測產品進行檢測外，還在於設計部份的USB-C傳輸埠具有電源雙重角色(Dual-Role Power，簡稱DRP)功能。詳細來說，USB-C(或稱Type-C)裝置除了可運作在用電或耗電(Sink)角色外，還可支援供電(Source)角色或用電供電雙角色(DRP)。當USB-C裝置作為用電(Sink)角色或用電端時，系統將從其上抽出電流；而當USB-C裝置作為供電(Source)角色或供電端時，系統對其供電或充電。於此實施例中，我們設計第一與第四個USB-C傳輸埠21、24具有DRP功能，而其他四個USB-C傳輸埠22、23、25、26則僅可作為用電(Sink)角色。 In addition to designing multiple USB-C transmission ports to detect multiple USB-C products to be tested at the same time, the present invention is also characterized in that the designed USB-C transmission ports have dual roles of power supply (Dual-Role Power, referred to as DRP) function. Specifically, a USB-C (or Type-C) device can not only operate in the role of power consumption or power consumption (Sink), but also support the role of power supply (Source) or dual role of power supply (DRP). When the USB-C device acts as a sink or a power source, the system will draw current from it; and when the USB-C device acts as a source or a power source, the system supplies or charges it. In this embodiment, we design the first and fourth USB-C ports 21, 24 to have DRP functions, while the other four USB-C ports 22, 23, 25, 26 are only used for power (Sink )Role.

請參見第2圖，為本發明所提出的產品檢測方法的流程圖。首先，使該至少一USB-C待測產品連接於該些USB-C傳輸埠，並使該至少一電源檢測儀器連接於該些檢測連接埠(步驟S1)；其次，由該檢測程式發出一檢測指令(步驟S2)；接著，由該處理單元檢查各USB-C傳輸埠的連接狀態(步驟S3)；接著，將連接有該USB-C待測產品的該USB-C傳輸埠設定為一第一角色或一第二角色(步驟S4)；接著，由該處理單元控制該第一角色的該USB-C傳輸埠循環運作在多個指定電壓上(步驟S5)，並對該第二角色的該USB-C傳輸埠輸出電壓(步驟S7)；最後，由所連接的該電源檢測儀器檢測在相應的該USB-C傳輸埠上的該USB-C待測產品的運作情形(步驟S6、S8)。 Please refer to FIG. 2, which is a flow chart of the product detection method proposed by the present invention. First, connect the at least one USB-C product to be tested to the USB-C ports, and connect the at least one power testing instrument to the testing ports (step S1); secondly, the testing program sends out a detection command (step S2); then, the processing unit checks the connection status of each USB-C transmission port (step S3); then, the USB-C transmission port connected with the USB-C product to be tested is set as a A first role or a second role (step S4 ); then, the processing unit controls the USB-C port of the first role to operate on a plurality of specified voltages cyclically (step S5 ), and the second role is the output voltage of the USB-C transmission port (step S7); finally, the connected power detection instrument detects the operation of the USB-C product under test on the corresponding USB-C transmission port (step S6, S8).

針對所述步驟S1，此實施例在此一階段之前是設計該產品檢測系統1處於初始狀態並準備開始進行檢測，而在初始狀態時，各USB-C傳輸埠21~26和各檢測連接埠31a~38b尚未有連接的情形。如上所述，使用者將需要檢測的USB-C待測產品對該些USB-C傳輸埠21~26做連接的方式是視其USB-C待測產品的輸出/輸入埠的設計而定。故USB-C傳輸埠與USB-C待測產品之間可能會呈現出一個傳輸埠對應一個待測產品的連接關係，或是多個傳輸埠對應一個待測產品的連接關係。 For the step S1, in this embodiment, the product testing system 1 is designed to be in an initial state and ready to start testing before this stage. In the initial state, each USB-C transmission port 21-26 and each testing connection port 31a~38b are not yet connected. As mentioned above, the manner in which the user connects the USB-C DUT to the USB-C ports 21 to 26 depends on the design of the output/input ports of the USB-C DUT. Therefore, between the USB-C port and the USB-C product under test, there may be a connection relationship in which one port corresponds to one product under test, or a connection relationship in which multiple ports correspond to one product under test.

另一方面，所使用的電源檢測儀器60對該些檢測連接埠31a~38b的連接方式也有類似的對應關係，也就是需視其儀器本身的檢測頻道數目和所要檢測的USB-C待測產品的數目、輸出/輸入埠的數目而定。完成連接的電源檢測儀器60需要再連接一外接電源方可開啟運作。 On the other hand, the used power testing instrument 60 also has a similar corresponding relationship to the connection methods of these testing connection ports 31a-38b, that is, it depends on the number of testing channels of the instrument itself and the USB-C product to be tested. , the number of output/input ports. After the connection is completed, the power detection instrument 60 needs to be connected to an external power source before it can start to operate.

針對所述步驟S2，如上所述，使用者可在該電腦裝置50上執行該檢測程式，並在所呈現的視窗介面中進行檢測控制。詳細來說，本發明的該產品檢測方法可設計成自動執行，當使用者利用該檢測程式進行控制而發出一檢測指令至該產品檢測裝置100時，該處理單元11就能接收該檢測指令而開始執行相應的運作程式碼以進行檢測。該檢測程式的設計目的在於監控，且所監控的是符合USB-C PD通訊協定的多個USB-C傳輸埠21~26，因此該檢測程式亦須根據USB-C電力傳輸(PD)通訊協定發出該檢測指令。 For the step S2, as described above, the user can execute the detection program on the computer device 50, and perform detection control in the presented window interface. In detail, the product detection method of the present invention can be designed to be executed automatically. When a user uses the detection program to control and sends a detection command to the product detection device 100, the processing unit 11 can receive the detection command and Start executing the corresponding operational code for detection. The testing program is designed to monitor and monitor multiple USB-C ports 21~26 that conform to the USB-C PD protocol. Therefore, the testing program must also be based on the USB-C Power Delivery (PD) protocol. Issue the detection command.

針對所述步驟S3，該處理單元11可依序對該些USB-C傳輸埠21~26進行檢查，用以查看哪些傳輸埠有連接的狀態。於此實施例中，此一階段已有USB-C傳輸埠21、22與相應的USB-C待測產品41、42形成連接，如此該處理單元11就可知後續的檢測要對哪些傳輸埠來進行。可以理解的是，此一階段亦可為一種判斷的程序。舉例來說，該處理單元11可檢查各傳輸埠有無形成連接的狀況；若有連接的狀況，就進行下一步程序；若沒有連接的狀況，可再重覆進行檢查。 For the step S3, the processing unit 11 can check the USB-C ports 21-26 in sequence to check which ports are connected. In this embodiment, at this stage, the USB-C transmission ports 21 and 22 are already connected to the corresponding USB-C products to be tested 41 and 42 , so that the processing unit 11 can know which transmission ports to target for subsequent detection. conduct. It can be understood that this stage can also be a judgment procedure. For example, the processing unit 11 can check whether each transmission port is connected; if there is a connection, the next step is performed; if there is no connection, the check can be repeated.

針對所述步驟S4，該第一角色的設定為使所連接的USB-C待測產品41、42對該電路板10進行供電，即所述的用電(Sink)角色。於此實施例中，設計所有的USB-C傳輸埠21~26均可提供於該第一角色的運作。因此，若要檢測USB-C待測產品41、42在用電(Sink)角色的運作情形，可將該USB-C待測產品41、42連接上該些USB-C傳輸埠21~26中的任一個。另外，該第二角色的設定為使該電路板10或一外接電源(未顯示於圖式)對所連 接的該USB-C待測產品41進行供電，即所述的供電(Source)角色。 For the step S4, the first role is set so that the connected USB-C products under test 41 and 42 supply power to the circuit board 10, that is, the role of the sink. In this embodiment, it is designed that all the USB-C ports 21-26 can be provided for the operation of the first role. Therefore, to detect the operation of the USB-C DUT 41 and 42 in the role of sink, the USB-C DUT 41 and 42 can be connected to the USB-C ports 21 to 26 any of the . In addition, the setting of the second role is such that the circuit board 10 or an external power supply (not shown in the figure) is connected to the The connected USB-C product under test 41 supplies power, that is, the role of the power supply (Source).

承上所述，本發明設計部份的USB-C傳輸埠還提供於該第二角色的運作，於此實施例中是設計第一與第四個USB-C傳輸埠21、24還可運作在該第二角色。換句話說，第一與第四個USB-C傳輸埠21、24可同時支援上述的DRP功能，而另一部份的傳輸埠，即其他四個USB-C傳輸埠22、23、25、26則只能運作在用電(Sink)的該第一角色。因此，若要檢測USB-C待測產品在供電(Source)角色的運作情形，則只能將其連接上USB-C傳輸埠21或USB-C傳輸埠24。 As mentioned above, the USB-C port in the design part of the present invention is also provided for the operation of the second role. In this embodiment, the first and fourth USB-C ports 21 and 24 are designed to also operate in that second role. In other words, the first and fourth USB-C ports 21, 24 can support the above-mentioned DRP function at the same time, while the other part of the ports, namely the other four USB-C ports 22, 23, 25, 26 can only operate in the first role of electricity (Sink). Therefore, to detect the operation of the USB-C DUT in the role of power supply (Source), it can only be connected to the USB-C port 21 or the USB-C port 24 .

更進一步來說，步驟S4的角色設定若是針對其他四個USB-C傳輸埠22、23、25、26的話，則可由使用者來完成，因為這些傳輸埠無法運作供電(Source)角色，使用者只要將待測產品連接上這幾個傳輸埠就可確定其固定在用電(Sink)角色。然而，若是連接到第一或第四個USB-C傳輸埠21、24時，其角色就可能為用電(Sink)或是供電(Source)。於此實施例中，這部份可以透過USB-C PD通訊協定來決定，也就是可根據需求來設定該次檢測是要在用電(Sink)或供電(Source)角色。 Furthermore, if the role setting in step S4 is for the other four USB-C ports 22, 23, 25, and 26, it can be done by the user, because these ports cannot perform the role of power supply (Source), and the user As long as the product under test is connected to these transmission ports, it can be determined that it is fixed in the role of sink. However, if it is connected to the first or fourth USB-C port 21, 24, its role may be either Sink or Source. In this embodiment, this part can be determined through the USB-C PD communication protocol, that is, whether the detection is to be in the role of sink or source can be set according to requirements.

針對所述步驟S5~S6，目前標準的Type-C傳輸線的電源供應在USB-C PD通訊協定下可支援多種電壓，即所述的多個指定電壓，包括5伏特(V)、9伏特(V)、12伏特(V)、15伏特(V)或20伏特(V)。本發明的其一特徵在於，針對用電(Sink)的該第一角色的檢測，該處理單元11會依序地對相應的USB-C傳輸埠21、22以該些指定電壓進行運作並重覆循環，使得該些USB-C傳輸埠21、22可從相應的USB-C待測產品41、42上以不同的指定電壓抽出電流，進而由該電源檢測儀器60檢測相應的USB-C待測產品41、42的負載能力。 For the steps S5-S6, the power supply of the current standard Type-C transmission line can support multiple voltages under the USB-C PD communication protocol, that is, the multiple specified voltages, including 5 volts (V), 9 volts ( V), 12 Volts (V), 15 Volts (V), or 20 Volts (V). A feature of the present invention is that, for the detection of the first role of power consumption (Sink), the processing unit 11 will sequentially operate the corresponding USB-C ports 21 and 22 with the specified voltages and repeat it Cycle, so that the USB-C transmission ports 21, 22 can draw current from the corresponding USB-C products 41, 42 under test with different specified voltages, and then the power detection instrument 60 detects the corresponding USB-C under test. Load capacity of products 41, 42.

承上所述，根據目前技術，標準的Type-C傳輸線額定的負載能力是3安培(A)。於此實施例中，我們可將該電源檢測儀器60設定以3安培(A)或4.25安培(A)的電流對相應的USB-C 待測產品41、42進行抽載，並循環搭配不同的指定電壓。 As mentioned above, according to current technology, standard Type-C transmission lines are rated at 3 amps (A). In this embodiment, we can set the power detection instrument 60 to connect the corresponding USB-C with a current of 3 amps (A) or 4.25 amps (A). The products 41 and 42 to be tested are loaded and cyclically matched with different specified voltages.

以第1B圖的USB-C待測產品41、42的應用為例，該處理單元11可依序使傳輸埠21運作在5伏特(V)、使傳輸埠22運作在5伏特(V)、使傳輸埠21運作在9伏特(V)、使傳輸埠22運作在9伏特(V)、使傳輸埠21運作在12伏特(V)、使傳輸埠22運作在12伏特(V)、使傳輸埠21運作在15伏特(V)、使傳輸埠22運作在15伏特(V)、使傳輸埠21運作在20伏特(V)、使傳輸埠22運作在20伏特(V)等方式。其次，該處理單元11可作自動循環控制和設計重覆的次數，藉由多次不同的輸出檢測以得到精確的檢測結果。當然，若有更多的USB-C傳輸埠連接上USB-C待測產品時，在這些USB-C傳輸埠上也可採用上述的循環方式來進行控制。 Taking the application of the USB-C DUTs 41 and 42 in FIG. 1B as an example, the processing unit 11 can sequentially enable the transmission port 21 to operate at 5 volts (V), the transmission port 22 to operate at 5 volts (V), Make port 21 operate at 9 volts (V), make port 22 operate at 9 volts (V), make port 21 operate at 12 volts (V), make port 22 operate at 12 volts (V), make transmission Port 21 operates at 15 volts (V), the transmission port 22 operates at 15 volts (V), the transmission port 21 operates at 20 volts (V), the transmission port 22 operates at 20 volts (V), and so on. Secondly, the processing unit 11 can perform automatic loop control and design the number of repetitions, and obtain accurate detection results through multiple different output detections. Of course, if there are more USB-C ports connected to the USB-C product under test, the above-mentioned cyclic method can also be used to control these USB-C ports.

另一方面，此實施例的該電源檢測儀器60也具有相關的操作介面與顯示單元，可提供使用者操作並能顯示出各頻道所測到的包括電壓、電流或運作功率等數據。再者，該電腦裝置50還可用另一傳輸線信號連接於該電源檢測儀器60，使得該電源檢測儀器60可同時將檢測USB-C待測產品41、42的檢測結果傳輸至該電腦裝置50上，而使用者可在該檢測程式所呈現的視窗介面上進行觀看。此外，若待測產品的數目愈多，或是所設計的循環次數愈多時，本發明還設計該電腦裝置50的該檢測程式可自動地將所接收到的數據再做進一步的整理與計算，而無需使用者再花時間來處理。 On the other hand, the power detection apparatus 60 of this embodiment also has a related operation interface and a display unit, which can provide user operation and display data including voltage, current or operating power measured by each channel. Furthermore, the computer device 50 can also be connected to the power testing instrument 60 by another transmission line signal, so that the power testing instrument 60 can simultaneously transmit the detection results of the USB-C products to be tested 41 and 42 to the computer device 50 . , and the user can view it on the window interface presented by the detection program. In addition, if the number of products to be tested increases, or the number of designed cycles increases, the present invention also designs that the testing program of the computer device 50 can automatically further organize and calculate the received data. , without the need for the user to spend time processing.

另一方面，所述步驟S7~S8亦有類似的流程，但步驟S7~S8是針對當USB-C傳輸埠為供電(Source)的該第二角色時的處理方式。以同樣的第1B圖來說，針對供電(Source)的該第二角色的檢測應用只有支援DRP功能的該USB-C傳輸埠21才可進行。如第1A圖和第1B圖所示，該電路板10還設置有可提供電源線的轉接頭連接的一電源插座13，使得電源線可從該外接電源(未顯示於圖式)上傳輸電力而能對作為該第二角色的USB-C傳輸 埠21所連接的USB-C待測產品41進行供電。 On the other hand, the steps S7-S8 also have similar processes, but the steps S7-S8 are for the processing method when the USB-C port is the second role of the power supply (Source). Taking the same FIG. 1B as an example, the detection application for the second role of the power supply (Source) can only be performed on the USB-C port 21 that supports the DRP function. As shown in FIG. 1A and FIG. 1B, the circuit board 10 is also provided with a power socket 13 which can provide an adapter connection for the power cord, so that the power cord can be transmitted from the external power supply (not shown in the figure) Power can be transferred to USB-C as this second role The USB-C product under test 41 connected to the port 21 supplies power.

於此實施例中，我們採用65瓦特(W)的外接電源來提供電力，並設定該電源檢測儀器60以3安培(A)或1.5安培(A)的電流對相應的USB-C待測產品41進行抽載，進而檢測其產品的供電能力。可以理解的是，包括該處理單元11在內的該產品檢測裝置100的運作電力也可由該外接電源提供。由於針對供電(Source)的該第二角色的檢測應用包括了對該USB-C傳輸埠21輸出電壓和由該電源檢測儀器60抽載電流以檢測其運作情形，故於第1B圖中示意其信號呈現出雙向傳輸。 In this embodiment, we use an external power supply of 65 watts (W) to provide power, and set the power detection instrument 60 to supply the corresponding USB-C product under test with a current of 3 amps (A) or 1.5 amps (A). 41 performs load extraction to detect the power supply capability of its products. It can be understood that the operating power of the product detection device 100 including the processing unit 11 can also be provided by the external power source. Since the detection application for the second role of the power supply (Source) includes the output voltage of the USB-C port 21 and the current drawn by the power detection instrument 60 to detect its operation status, it is shown in FIG. 1B. The signal exhibits bidirectional transmission.

由上述說明可知，該第一角色和該第二角色的檢測無法同時進行，特別是此實施例中可支援DRP功能的第一與第四個USB-C傳輸埠21、24。為了有效規劃檢測工作，在第1B圖中可先進行完USB-C傳輸埠21、22運作該第一角色的檢測後，再單獨對USB-C傳輸埠21進行運作該第二角色的檢測。進一步來說，本發明在步驟S5~S6的該第一角色檢測流程和步驟S7~S8的該第二角色檢測流程兩者之間並沒有一定的先後關係，使用者可依需求決定要先進行對該第一角色或是對該第二角色的檢測。或者，可設計當該處理單元11完成對該第一角色的檢測之後，還會自動地再接續進行對該第二角色的檢測。 It can be seen from the above description that the detection of the first role and the second role cannot be performed simultaneously, especially the first and fourth USB-C ports 21 and 24 that can support the DRP function in this embodiment. In order to effectively plan the detection work, in FIG. 1B, the detection of the USB-C transmission ports 21 and 22 operating the first role can be performed first, and then the USB-C transmission port 21 can be independently detected to operate the second role. Further, in the present invention, the first character detection process in steps S5-S6 and the second character detection process in steps S7-S8 do not have a certain sequence relationship, and the user can decide to perform Detection of the first character or the second character. Alternatively, it can be designed that after the processing unit 11 completes the detection of the first character, the detection of the second character is automatically continued.

再者，第1B圖還示意了本發明的該產品檢測裝置100還包含有同樣設置於該電路板10上的一手動操作組件14及一顯示組件15，其中該手動操作組件14能夠提供使用者以手動操作的方式進行檢測，而該顯示組件15則被設計為除了能顯示和反應出使用該手動操作組件14的檢測結果外，亦能同時顯示和反應出以該檢測指令進行檢測的檢測結果。 Furthermore, FIG. 1B also shows that the product detection device 100 of the present invention also includes a manual operation component 14 and a display component 15 also disposed on the circuit board 10 , wherein the manual operation component 14 can provide the user with The detection is performed by manual operation, and the display component 15 is designed to display and reflect the detection result using the manual operation component 14 and the detection result using the detection instruction at the same time. .

詳細來說，該手動操作組件14可被設計為是一種能提供使用者進行撥動操作的一切換開關140，且該切換開關140可由搭配USB-C傳輸埠21、24的多組開關所構成，從而能夠由使用者來設定是否致能USB-C傳輸埠21、24的該第二角色或DRP 功能的運作。其次，該手動操作組件14還可被設計為是一種能提供使用者進行按壓操作的多個按鍵141~143，從而能夠由使用者來進行多個不同指定電壓的運作控制。該顯示組件15則可採用多個LED元件，使用者可藉由其燈號的顏色或閃爍的情形來瞭解手動操作或自動檢測的結果。 Specifically, the manual operation component 14 can be designed as a switch 140 that can provide a toggle operation for the user, and the switch 140 can be composed of multiple sets of switches matched with the USB-C ports 21 and 24 , so that the user can set whether to enable the second role or DRP of the USB-C ports 21 and 24 function operation. Secondly, the manual operation component 14 can also be designed as a plurality of buttons 141 to 143 that can be pressed by the user, so that the user can control the operation of a plurality of different specified voltages. The display assembly 15 can use a plurality of LED elements, and the user can know the result of manual operation or automatic detection by the color or flashing status of the light signal.

本發明的該手動操作組件14可同時包括了該切換開關140與該些按鍵141~143這兩種硬體的設置。該手動操作組件14與該顯示組件15皆電連接於該處理單元11，從而能將使用者設定或控制的結果告知該處理單元11，或可接收與顯示出該處理單元11所發送的信息。 The manual operation component 14 of the present invention may simultaneously include two hardware settings of the switch 140 and the buttons 141 to 143 . Both the manual operation component 14 and the display component 15 are electrically connected to the processing unit 11 , so as to inform the processing unit 11 of the result set or controlled by the user, or receive and display the information sent by the processing unit 11 .

現以一第二實施例進行本發明的說明，請參見第3圖，為本發明的該產品檢測系統1進行USB-C與Type-A檢測應用的示意圖。此第二實施例與第一實施例的主要差異在於，如第3圖所示，此第二實施例的該產品檢測裝置100與該產品檢測系統1所進行的是對一Type-A/C待測產品43之檢測。換言之，該Type-A/C待測產品43除了具有USB-C(或稱Type-C)類型的傳輸介面外，還具有Type-A的傳輸介面。根據目前技術，此類裝置所設計的輸出/輸入埠可不只有一個，而此種裝置可例如為電源擴充基座(Docking Station)、USB轉接/集線器(Hub)、多埠的USB電源轉接裝置等。 Now, a second embodiment is used to describe the present invention. Please refer to FIG. 3 , which is a schematic diagram of the USB-C and Type-A detection application of the product detection system 1 of the present invention. The main difference between the second embodiment and the first embodiment is that, as shown in FIG. 3 , the product testing device 100 and the product testing system 1 of the second embodiment perform a Type-A/C Inspection of the product to be tested 43. In other words, the Type-A/C product under test 43 not only has a USB-C (or Type-C) type transmission interface, but also has a Type-A transmission interface. According to the current technology, such devices may be designed with more than one output/input port, and such devices may be, for example, a docking station, a USB adapter/hub, or a multi-port USB power adapter. device etc.

如在上述第一實施例中所提的，該產品檢測裝置100還具有兩Type-A傳輸埠27、28而可提供Type-A待測產品連接與檢測。其次，雖然在第3圖中未示出，但可以理解的是該產品檢測裝置100還具有設置在該電路板10上並分別對應Type-A傳輸埠27、28的多工器(MUX)，用以對該些Type-A傳輸埠27、28進行輸出的選擇或切換。所述的各多工器是分別電連接於該些Type-A傳輸埠27、28與該處理單元11之間。 As mentioned in the above-mentioned first embodiment, the product testing apparatus 100 also has two Type-A transmission ports 27 and 28 to provide connection and detection of Type-A products to be tested. Secondly, although it is not shown in FIG. 3, it can be understood that the product detection device 100 also has a multiplexer (MUX) disposed on the circuit board 10 and corresponding to the Type-A transmission ports 27 and 28, respectively. It is used to select or switch the output of these Type-A transmission ports 27 and 28 . The multiplexers are respectively electrically connected between the Type-A transmission ports 27 and 28 and the processing unit 11 .

於此實施例中，該Type-A/C待測產品43具有四個輸出/輸入埠，其中的三個為USB-C類型，例如為15瓦特(W)、 18瓦特(W)、85瓦特(W)三種不同運作功率；而另一個為Type-A類型，運作功率可為7.5瓦特(W)(提供5伏特(V)/1.5安培(A)之運作)。該些Type-A傳輸埠27、28可進行符合USB電池用途充電(BC)規範的負載或用電檢測，且特別是針對USB電池用途充電(BC)版本為1.2的規範。 In this embodiment, the Type-A/C product under test 43 has four output/input ports, three of which are USB-C type, such as 15 watts (W), 18 watts (W), 85 watts (W) three different operating power; and the other is Type-A type, the operating power can be 7.5 watts (W) (providing 5 volts (V) / 1.5 amps (A) operation) . The Type-A ports 27 and 28 can perform load or power detection in compliance with the USB Battery Charging (BC) specification, and especially for the USB Battery Charging (BC) version 1.2 specification.

承上所述，該Type-A/C待測產品43以三條傳輸線連接於該產品檢測裝置100的第一至第三個USB-C傳輸埠21~23，並以另一條傳輸線連接於該產品檢測裝置100的Type-A傳輸埠27。其次，此實施例的該電源檢測儀器60因設計有多個檢測頻道，故該電源檢測儀器60可對第一至第三個USB-C傳輸埠21~23和該Type-A傳輸埠27所相應的檢測連接埠31a、31b、32a、32b、33a、33b、37a、37b分別以八條傳輸線加以連接。 As mentioned above, the Type-A/C product under test 43 is connected to the first to third USB-C transmission ports 21 to 23 of the product detection device 100 by three transmission lines, and is connected to the product by another transmission line The Type-A transmission port 27 of the detection device 100 is detected. Secondly, since the power detection instrument 60 of this embodiment is designed with multiple detection channels, the power detection instrument 60 can detect the first to third USB-C transmission ports 21 to 23 and the Type-A transmission port 27 The corresponding detection connection ports 31a, 31b, 32a, 32b, 33a, 33b, 37a, 37b are respectively connected by eight transmission lines.

是以，當該電源檢測儀器60在對該Type-A/C待測產品43進行包括用電(Sink)的該第一角色和供電(Source)的該第二角色的檢測時，另一方面亦可由該處理單元11檢查各Type-A傳輸埠27、28的連接狀態。接著，於此實施例中，可設計由該電源檢測儀器60根據電池用途充電(BC)規範來檢測在該Type-A傳輸埠27上的該Type-A/C待測產品43相應的輸出/輸入埠的運作情形。詳細來說，該電源檢測儀器60可採用USB的D+/D-可切換式分壓的辨認技術來進行包括電壓或電流項目的檢測，且可將該電源檢測儀器60設定以3安培(A)、1.5安培(A)或4.25安培(A)的電流對該Type-A/C待測產品43進行抽載。 Therefore, when the power detection instrument 60 detects the Type-A/C product under test 43 including the first role of power consumption (Sink) and the second role of power supply (Source), on the other hand The connection status of each Type-A transmission port 27 and 28 can also be checked by the processing unit 11 .
